Broadband service transmission by local area network

Nortel Vietnam's new network solution allows service providers to use Ethernet, the PC-connected architecture in the local area network (LAN), as a tool to deliver broadband services such as IPTV, mobile video and other services. wide-ranging enterprise services.

The main objective of the technology lies in the standardization of Provider Backbone Bridging (PBB) and the overall exploitation, management and maintenance tools. Metro Ethernet is made up of many solutions, from access to core network and long distance solutions. Combining the high-density capability of Ethernet protocols and optical network connectivity, service providers can build a comprehensive Metro Ethernet (End-to-end) network with a variety of technologies.

Nortel experts' reviews show that Internet usage is moving away from the original target, which is reflected in three trends. The first is the development of online video in any form. The company's survey 2 months ago showed that up to 60% of Internet traffic is now reserved for viewing or uploading / downloading videos. The second trend is the independence between infrastructure and applications. Finally, the penetration of IT into the entertainment sector, not just business as before. Therefore, the old network architectures are " short of breath " before new applications.

"The current wide area network architecture has a slow response, the ability to troubleshoot often from 1 to 5 seconds. That can interrupt a VoIP conversation," said Anup Changaroth, Metro Product Marketing Manager. Nortel's Ethernet, said. "Nortel's new network solution has the ability to automatically detect errors and recover in 50 milliseconds. That moment the user can't recognize it."
